摘要： A toroidal continuously variable transmission includes a rotating shaft, a pair of discs, at least one power roller, and at least one bearing arranged between the rotating shaft and a casing. At least one of the pair of discs includes: a disc main body including a concave surface opposed to the power roller; and a cylindrical portion projecting from the disc main body along the rotation axis toward an opposite side of the power roller. The cylindrical portion is inserted between the bearing and the rotating shaft.

摘要： A power generation controller of an aircraft includes a low-temperature start-up control section and a power generation control section. When it is determined that an oil temperature of a hydraulic actuator configured to change an operation position of a speed change element of a hydraulic transmission satisfies a predetermined low-temperature condition when starting up an aircraft engine, the low-temperature start-up control section sets a power generator to a power non-generating state and controls the hydraulic actuator such that the speed change element is positioned at an acceleration side of a median in a speed change range. When it is determined that the oil temperature satisfies a predetermined low-temperature start-up completion condition, the power generation control section sets the power generator to a power generating state and controls the hydraulic actuator in accordance with a rotational frequency of the aircraft engine.

摘要： Traction transmission having a first and a second component transmission (26a, b) which are of mirror-symmetrical construction with respect to one another and are arranged axially adjacently in a housing (12), in each case comprising—an axially inner drive friction disc (28a, b) and an axially outer complementary friction disc (32a, b) which are arranged coaxially and can be rotated relative to one another about a transmission central axis, and—a set of friction rollers (40) which make non-positive contact between the friction discs (28a, b, 32a, b) and are mounted such that they can be rotated about in each case one roller axle (44), wherein the roller axles (44) are pivotably mounted in a manner which is spaced apart radially from the transmission central axis on a star-shaped spider (38a, b) which can be moved ax Lilly in relation to the transmission central axis, wherein the spiders (38a, b) are arranged on a common spider sleeve (50) and are coupled to one another at a variable spacing via an axially extending thread pairing (52), wherein—the complementary friction discs (32a, b) are arranged fixedly on a common output shaft (34) which is mounted in the housing such that it is fixed axially and can be rotated, —the spacing of the drive friction discs (28a, b) from one another can be varied by means of a spacing setting device (60), and—the spider sleeve (50) is mounted such that it can be displaced axially relative to the housing (12), wherein the first spider (38a) which is assigned to the first component transmission (26a) is connected fixedly to the housing (12) so as to rotate with it, the second spider (38b) which is assigned to the second component transmission (26b) can be rotated relative to the housing (12) by means of an angular position setting device (54b, 58), and the thread pairing (52) which couples the spiders (38a, b) is set up in such a way that a relative rotation of the spiders (38a, b) brings about a change in the spacing thereof.

摘要： A variator comprises first and second races disposed for rotation about a variator axis and at least one rolling element disposed in a cavity between the races. In a drive configuration, drive is transmitted between the races and the at least one rolling element; and in a neutral configuration, the at least one rolling element and races are configured whereby the races can move independently of one another. In a method of operating the variator, the neutral configuration is obtained by moving the at least one rolling element to a position in which it ceases to make contact with at least one of the races. The drive configuration is obtained by moving the at least one rolling element to a position in which it makes contact with both of the races.

摘要： Provided is a pressing device for a toroidal continuously variable transmission that is capable of sufficiently supplying lubrication oil to all rollers inside a pocket, and is capable of suppressing the occurrence of fretting wear on the rolling surfaces of the rollers, a first cam surface and a second cam surface. An oil passage 28 is provided for supplying lubrication oil to the inside of each pocket 25 in the inside portion in the radial direction of a retainer 14 that holds a plurality of more than one roller 13 arranged in a row in the radial direction. The center axis O29 of a discharge port 29 that is provided on an end portion on the downstream side of the oil passage 28 and that opens to the inside surface in the radial direction of the pocket 25 is inclined toward the front side in the rotational direction of the retainer 14 with respect to the center axis of the pocket 25.

摘要： Methods, systems, and devices describe bi-triaxial photoconductive switch modules that that eliminate the need for external DC blocking capacitors, while providing a highly compact structure that can produce bipolar output waveforms conducive to feeding to radio-frequency (RF) devices, such as antennas. Some implementations of the disclosed bi-triaxial photoconductive switch modules utilize unified cast-in-place capacitors that can be designed with an appropriate geometry, volume and orientation to provide desired energy storage capacity while eliminating or reducing parasitics.
